Ice streams are actually streams of ice that circulate a lot quicker compared to their settings. They are actually the areas along which many of the ice in Antarctica is actually supplied towards the sea, and also consequently changes in their rate can easily have an effect on the water level. If the extra "lubricant" given through a number of volcanic eruptions was actually channelled under ice streams, the succeeding swift circulate might dumping ground uncommon quantities of West Antarctica's thick indoor ice right in to the sea, inducing ocean amounts towards growth.
